Inventor: IIO TAKAYUKI
IPC: F01C21/00
Filed: 1991-06-11
Abstract: 7. ABSTRACT         The present invention relates to a scroll type fluid machinery provided with a slide type radius of revolution variable mechanism, and has an object of pre-venting unilateral working of a rotating bearing 23 due to tilted rotation of a drive bushing 21 and a balance weight 27 fixed thereto.         The construction of the present invention is formed in such a manner that a bolt 41 for regulating tilted rotation is projected at an inner end of a rotary shaft 7, a shaft portion 41a thereof is made to penetrate through a vain hole 42 bored in the balance weight 27, and a bearing surface 41c of a head 41b thereof is brought into slidable contact with the inner end surface of the balance weight 27.  When the radius of revolution is varied at the time of revolution in a solar motion of a revolving scroll 14, an eccentric driving pin 25 slides in a slide groove 24 and the shaft portion 41a of the bolt 41 slides in the vain hole 42 at the same time.          In the interim, the bearing surface 41c of the head 41 comes into slidable contact with the inner end surface of the balance weight 27, thereby to suppress tilted rotation of the balance weight 27.

Filed: 1991-08-12
Abstract: ABSTRACT OF THE DISCLOSURE          The present invention is a sewage clean-out line cover and removable cap made of Ultra High Molecular Weight Polyethylene.  The interior of the cover carries a plurality of rows of upwardly inclined teeth, the rows being parallel and unconnectable to each other.  The teeth comprising each row have a pitch to depth ratio of approximately 1:1.  The ratio of the slope of the upper surface of the teeth to the lower surface is 1:1, thus providing a tip for installation over the open end of the upstanding clean-out pipe which tip is flexible for pushing the cover over the open end of the clean-out pipe due to the inherent lubricity of the UHMWPE but which resists removal of the cover by the tips folding over to increase friction against the clean-out pipe outer surface.  The cover is usable with cast iron or PVC pipe or any other presently known material used to form sewage clean-out pipes.  A second embodiment of the present invention includes a magnet inserted in the upper surface of the cover and selectively may include an additional magnet into the upper surface of the removable cap.

Title: Method of and system for supplying electric power to water discharge apparatus
Inventor: SHIBA MASASHI
IPC: G01V8/12
Filed: 1991-08-30
Abstract: ABSTRACT OF THE DISCLOSURE            An electric power supply system is provided for an automatic water discharge device for discharging water to flush the basin.   An object detector detects a person before the basin.   A brightness detector, which consumes less electric power than the object detector, detects a brightness surrounding the basin.  An electric power is supplied to the object detector on a power supply cycle so as to intermittently render it operative and to the brightness detector on a brightness detect cycle.  The brightness detect cycle is longer than the power supply cycle.  After a set time period following disappearance of a person from the basin, the electric power is, on one hand, shut off from the object detector to render it inoperative and, on the other hand, supplied to the brightness detector on the brightness detect cycle immediately after the shut off of electric power to the object detector, to detect a brightness surrounding the basin.  When the brightness detector detects a brightness higher than a predetermined brightness, the supply of electric power is resumed on the power supply cycle for the object  detector.

Title: Optical fiber circumferentially symmetric fusion splicing and progressive fire polishing
Inventor: PIKULSKI JOSEPH L
IPC: B23K26/40
Filed: 1992-01-24
Abstract: OPTICAL FIBER CIRCUMFERENTIALLY SYMMETRIC FUSION SPLICING AND PROGRESSIVE FIRE POLISHING               ABSTRACT OF THE DISCLOSURE         Two  optical  fiber segments are spliced in an end-to-end  fashion  by  first  axially  aligning the optical  fiber  segments, and then fusing the optical fiber  segments with a converging conical light beam convergently  focused  to  an  apex  region along the optical  fiber.    The  converging conical beam heats the  optical  fiber  segments  and  the  splice  in a circumferentially  uniform  manner.   The apex region at  which  the converging conical beam is focused can be  moved  progressively  along  the  length  of  the optical  fiber  to  effect  the  fusion,  and also to directionally  fire  polish  and  stress  relieve the optical  fiber  to  minimize the presence of flaws in the  optical  fiber  after  fusion  is complete.  The converging   conical   light   beam  is  achieved  by creating  a  diverging  conical  beam  using  movable mirrors   to   deflect   a  collimated  beam  into  a diverging  conical  beam.  The diverging conical beam is  reflected  from  a  parabolic  mirror to form the converging  conical  beam  that is focused toward the optical  fiber.    Longitudinal  movement of the apex region   along  the  optical  fiber  is  achieved  by altering   the  amplitude  of the  movement  of  the mirrors  to  change  the  apex angle of the diverging conical light beam.

Abstract: This interface connection through a hole (2) in a high-temperature-resistant and vacuum-proof insulating part (1), particularly of ceramic, glass, or a single crystal, consists of a metallic Lead (4, 17) inserted into the hole (2) and having a coefficient of thermal expansion less than that of the insulating part (1), wherein at least one end of the lead, if it is flush with at least one surface of the insulating part, is covered with active brazing material which high-vacuum-seals it to the insulating part, or, if it projects beyond at least one surface of the insulating part, is high-vacuum-sealed to the insulating part by means of ring-shaped active brazing material (5'), since in the liquid phase, the active brazing material moves into the gap between the wall of the hole (2) and the lead (4, 17) due to  capillary action. Thus, the available materials (insulating material, metals having a smaller coefficient of thermal expansion than the insulating part, active brazing materials) can be used in a different and novel manner such that the use of a lead covered with active brazing material can be dispensed with.

Title: Reactor system for suspension polymerization of vinyl chloride
Inventor: AMANO TADASHI
IPC: B01J19/24
Filed: 1992-07-02
Abstract: An improvement is proposed in a polymerization reactor system for the suspension polymerization of vinyl chloride monomer comprising a reactor and an external heat exchanger connected to the reactor by a pipe line through a pumping means in order to supplement the deficiency in the cooling capacity of the jacket of the reactor and/or reflux condenser installed thereto when the capacity of the reactor is greatly increased. While such an external circulating circuit using a conventional pump suffers from a serious problem of polymer scale deposition on the inner walls of the circuit and degradation of the quality of the resin product, these drawbacks can be dissolved by using a specific pump having an impellor in the form of a single spiral screw blade around a hub having a conical configuration for the circulation of the polymerization mixture through the heat exchanger.
